Hello B.Fest. New to the site, tons of information....seems mostly negative but im sure we mostly come here for answers to problems. at least thats what im telling my wife as she periodically leans over my shoulder....wanting me to come eat dinner. just purchased a 06' M5 yesterday. absolutely beautiful and fun. I looked thoroughly thru 5 pages of threads and found nothing on exhaust so i figured thats a sign it time for my first post. whats the deal with exhaust? what sounds best? im going to put a CAI on it this week or next to get her breathing going. but what next? wheres my next move? is it Dinan? Meistershaft? Eisenmann? im relying on youtube videos right now but i can only tell so much thru speakers. seems like dinan is the top brand but i think M.shaft sounds best. Whats the consensus? Thank you in advance everyone!
